That will bring down sooooo many trees in that area. HWY 3 and 101 will be shut down. 

Luckily they are wind sheltered so that will help.

18z EURO really increased QPF for the overrunning event…imagine the alarm will start to be sounded if the 00z sticks with it. Regional ice storm.

Consistent 1+ inch ice totals in the Gorge coupled with 50+ mph winds will not make for a good time

After February 2021 I think 1/2” of ZR is nothing. 
 

The January 2004 ice storm was actually extremely damaging at Silver Falls. The loop trail was closed in sections for a year or so afterwards. 

[Hawksfan2008]

 Drastic increase in precip for the overrunning event. Hopefully it’s just one shift and not a trend. 18z vs 12z.

Well thats not good!

One thing is for sure, it has not been a dull season so far!

Next week will probably have coastal wind warnings and localized flooding.

And we're just getting started! 

[Requiem]

Someone mind posting a localized view of PDX and the Gorge on that ice map if possible?

[MR.SNOWMIZER]

With all the offshore flow and a cold airmass I would think we could cool the column enough to support snow. I'm not to familiar with ice storms so I'm not sure. But there will be evaporate cooling so maybe it will just be a sleet or snow storm for the sound. An ice storm like that is pretty much unheard of up here.

[SilverFallsAndrew]

Down to 39 at Astoria, cooler air filtering in to NW Oregon now.

I'm thinking the NWS should issue a winter weather advisory for the Central Puget Sound area tonight.  I'm also puzzled about how they have no mention of possible strong east winds in the EPSL forecast beginning Wednesday night.

You will have to go up 4000' in PDX for the general snow level so I doubt anywhere west of the cascades will stay snow for long.

Ain't that the truth.  I'm going to be ready for a breather after Friday.

When does the event start/end for Puget Sound?  Does it end because the moisture dies or it rises above freezing?   

[Kayla]

The snow depth and piles around Bozeman are the highest I've ever seen them for this early in the winter. This is the parking lot at the mall and the piles are probably almost 20ft high.

 

[Doinko]

The WRF is forecasting 75mph+ gusts in east Portland Thursday night

Yeah I’m waiting for a high wind watch for the EPSL soon…

[snow_wizard]

It's probably worth mentioning the models hint at some of the cold east winds being shunted down toward Tacoma on the models.  I don't think it will be a Feb 2006 type thing though.  It seems like the east winds behave a bit differently when very cold air is in play.

[Doinko]

It's also been consistently showing 55mph+ gusts in my area on Thursday in the west metro

The main event is supposed to be midnight to 6am ish.  Moisture dies.  Cold will not be a question.

[MossMan]

I wish this week would last until the second week of March!

I was actually thinking it looks the most like that kind of setup since Feb 2006.

I really hope that doesn't happen for you guys.  The trees here are somewhat used to handling ice due to past events, but I'm betting yours aren't.

~7pm convergence zone pops up over the EPSL and works that way. Plenty cold.  

[Doinko]

Could someone post a map of ice from the GEM?

I remember the 500mb level trough back dug sharper on that one.  I was expecting horrible winds here and got off somewhat easy.  I think I peaked around 40mph with a temp of 23 with that.

Would be so nice to just have a ridge move in over us for a week starting late in the week, but not in the cards this time.

What happened in Feb 2006? I was still a kid lol

I'll be interested to see what kind of wind speeds Corbett puts up later in the week.

[WildrootParable]

Our burst of snow seems to have ended for now. It gave us a nice refreshing 1/2-1 inch of powder to make up for the melting earlier today. If that's all we get tonight, I would MUCH rather wake up to that than the horrible drip-drip-drip from this morning.

Thanks. This would be very bad

PDX gusted to 56 with that one-- I wouldn't be shocked if PDX does clock a 50 pluser. 

[Doinko]

Thought I'd post this.
